How we add common functionality to different extended Marionette classes.

base-view.js

		Module.WreqrMixin = function(obj) {
			return _.extend(obj, {
				setupWreqr: function() {
					var _this = this;

					this.reqres = new Backbone.Wreqr.RequestResponse();
					this.commands = new Backbone.Wreqr.Commands();

					this.request = function() {
						return _this.reqres.request.apply(_this.reqres, arguments);
					};

					this.hasRequestHandler = function(name) {
						return _this.reqres.hasHandler(name);
					};

					this.setRequestHandler = function() {
						_this.reqres.setHandler.apply(_this.reqres, arguments);
						return _this;
					};

					this.execute = function() {
						return _this.commands.execute.apply(_this.commands, arguments);
					};

					this.hasExecuteHandler = function(name) {
						return _this.commands.hasHandler(name);
					};

					this.setExecuteHandler = function() {
						_this.commands.setHandler.apply(_this.commands, arguments);
						return _this;
					};

					return this;
				},
			}).setupWreqr.apply(obj);
		};

		Module.ListView = Marionette.ItemView.extend({
			constructor: function(options) {
				Marionette.ItemView.prototype.constructor.apply(this, arguments);

				Module.WreqrMixin(this);
				return this;
			},

		});

		Module.LayoutView = Marionette.Layout.extend({
			constructor: function(options) {
				Marionette.Layout.prototype.constructor.apply(this, arguments);

				Module.WreqrMixin(this);
				return this;
			},
		});
